Abstract
Single concurrent plasma and lumbar spinal fluid samples were collected from twenty-two patients given IV dixyrazine 0.15 mg/kg, 10–106 min earlier in an open study.
Dixyrazine penetrated rapidly into the spinal fluid; the CSF/P ratio was 0.3 by 10 min after drug administration and persisted at that level during the study period. The uncontrolled sedative and anxiolytic effects assessed by the patients were slight, and were correlated with the CSF drug concentrations only during the first 30 min after medication.
